# GUGA vs KeyMemo

The clearest difference is device support: GUGA at 3 against KeyMemo's 1. GUGA also leads on iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. GUGA sells 3 one-off in-app purchases and KeyMemo sells 1 in-app purchase, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
